Operation in General 1 Introduction 1.1 Preface The Electronic Program Guide (EPG) service in digital satellite broadcasting is provided in accordance with the ordinances and announcements of the Ministry of Internal Affairs and Communications and the provisions of the Association of Radio Industries and Business (hereafter referred to as ARIB) Standard, "Service Information for Digital Broadcasting System" (ARIB STD-B10). However, for extensive and wide-range utilization of this Standard, more detailed provisions have been required separately. Hence this volume "Operational Guidelines for Digital Satellite Broadcasting PSI/SI" has been established. The standards for sending transmission control information specified in this document are designed to ensure the flexibility of program schedule for each trusted broadcaster and the expandability towards the future development of broadcasting services. Trusted digital satellite broadcasting companies are required to send PSI/SI in accordance with the provisions defined in this document. BS digital broadcast receivers are required to have an ability to receive signals sent in accordance with this document. In addition, enough care should be taken so that a malfunction will not occur due to signals that are not specified in this document. 1.2 Purpose This volume defines the standards for transmission in digital satellite broadcasting in compliance with the ARIB Standard STD-B10 "Service Information for Digital Broadcasting System". 1.3 Scope These provisions apply to the structures of PSI and SI, signal types, basic data structures, the use of identifiers and transmission standards used in digital satellite broadcasting. These provisions have binding force, as described below: [Receiving end] This provision document defines the specifications for PSI/SI transmission operation in digital satellite broadcasting and it does not force receivers to be implemented in compliance with this operation. However, if the receiving end demands operations that are not specified in this document, there is no guarantee that entrusted broadcast companies respond to the demand. [Sending end] These provisions are basically not enforceable on the sending end, either. However, if transmission is not performed in accordance with these provisions, normal operation in receivers is not guaranteed. 4-1

Association of Radio Industries and Business. Organization that standardizes the techniques regarding the domestic use of radio waves, with the participation of broadcasting companies, telecommunication carriers and manufactures. BAT describes the Bouquet name and information on the included service channels. BAT is not used in digital satellite broadcasting for the time being. Binary-coded decimal number BIT describes broadcaster configuration information. SI transmission parameters for commonly operated SI and each SI are described. Conditional access system. System that controls the viewing of services (service channels) or events (programs). Essential for chargeable broadcasting. Conditional access table. CAT specifies the packet ID of the TS packet that transmits individual information out of the related information comprising conditional access broadcasting. When a viewer selects a scrambled channel and he/she is not a subscriber, the CA alternate service directs the viewer to the "information channel". Continuity index. A 4-bit field that is incremented for each TS packet with the same PID Cyclic error detection code. CC is a cyclic redundancy check code used to verify the validity of data. Field that indicates display mode at reception, such as forced display or selective display. DRCS transmits external characters (Gaiji) in patterns. DRCS is used in the character coding standards for text/data broadcasting. Abbreviation for Digital Transmission Content Protection. DTCP is the standard for secure content transmission and recording control scheme using authentication and encryption in the digital interface. Decoding time stamp. Time management information for stream decoding. Common information that consists of program information (program-related information and descramble key) and control information (forced on/off of the decoder s scrambling function) Event information table. EIT describes program-related information such as program name, airdate and program content. Individual information including a work key to decipher contract information of each subscriber and common information Individual or common message transmitted by EMM. Electronic program guide. EPG is program information configured by a receiver using the SI sent from the broadcast station. EPG is used for program selection. 4-3

4 Coding of Character Strings The character codes and control codes that can be used in PSI/SI are based on the 8-bit code system defined in Part 2 of Volume 1 of ARIB STD-B24 "Data Coding and Transmission Specification for Digital Broadcasting". However, because of the nature of program information, there may be cases where characters that need rights-related and global considerations (such as personal name, place name, and original program title) have to be expressed in EPG or other information disply. JIS level 1 and level 2 defined in ARIB STD-B24 Kanji Set cannot not sufficiently deal with this problem and have a significant disadvantage even for paper media. Hence, a character set with more character types has been demanded. In digital satellite broadcasting, the implementation of features must be defined in accordance with ARIB STD-B24 while taking account of sharedness, compatibility and expandability with receivers that do not support JIS level 3 and 4 (JIS X0213: 2004). Whether receivers should be equipped with JIS levels 3 and 4 Kanji is left as a product planning matter. In addition, it is decided not to use external characters that ues DRCS because the operation of external characters that use DRCS will be inevitably complicated. Complication is due to the facts that program information of all stations must be simultaneously transmitted in commonly operated TS as commonly operated SI, and that EPG is presentation-free. 4.1 Character Set The character sets used in SI are as follows. G0, G1, G2 and G3 are called into the 8-bit code table (GL or GR) by call control. In addition, one code set out of a collection of code sets is specified as G0, G1, G2 and G3 by specification control of code sets. Table 4-1 lists the character sets used in SI. Table 4-1 Character Sets Used in SI (Code Set) Character code set JIS compatible Kanji Plane 1 (2-byte code) See "Appendix E". *1 JIS compatible Kanji Plane 2 (2-byte code) See "Appendix E". Alphanumeric (1-byte code) ARIB STD-B24 Hiragana (1-byte code) ARIB STD-B24 Katakana (1-byte code) ARIB STD-B24 Special symbol (2-byte code) See "Appendix E". *1 Because ARIB STD-B24 allows Kanji set to be allocated on this plane even when JIS X0213:2004 is not used, the Kanji set is set on this plane. However, the additional symbols traditionally defined in sections 90 to 94 should not be allocated on this plane. * DRCS code set Not used. * Macrocode set Not used. 4-10

4.2 Control Code Table 4-2 lists control codes used in each character string field in a descriptor, and Table 4-3 shows call control. Table 4-4 shows code specification control. Table 4-2 Control Codes Used in SI APR Line feed at operation position LS1 Call code set 1 (locking shift) LS0 Call code set 0 (locking shift) SS2 Call code set 2 (single shift) ESC Extended code system SS3 Call code set 1 (single shift) SP Space MSZ Specifies middle size (half-width). However, only alphanumeric characters (1-byte codes and 2-byte codes defined in Table 8-2 of ARIB STD-B5) and space (section 1 point 1 0x2121 and 0x20) can be specified. NSZ Specifies standard size (full-width) XCS(CSI) Defines alternate code string (*1) *1 XCS is alternate-code-string definition defined as the CSI extended control code (ARIB STD-B24 Volume 1). Essentially, XCS is used to display an alternative when DRCS cannot be displayed. However, if a receiver does not support JIS level 3 and level 4 and cannot display a JIS level 3 or level 4 Kanji code, the receiver displays a code string in the sequence placed immediately after the Kanji code. When displayed normally, the code string from the start to the end of the definition will be ignored. If a code that is not defined in Table 4-1 or a level 3 or level 4 kanji code is to be sent, an alternate code string defined with XCS must be sent immediately after each character. Therefore, the receiver, displays the alternate character placed immediately after an unsupported character code without displaying the code. At the end of transmission, the transmitting side should restore the original code set. Code sequence: CSI P1 I1 F CSI : 09/11 (Control sequence introducer) P1 : 03/0 Start of definition 03/1 End of definition I1 : 02/0 (Intermediate character) F : 06/6 (Termination character) 4-11
